provided at its lower edge with horizontal anges b, adapted to rest uponthe top plate of the stove about the margins of the hole ld therein. Thetop of the burner is closed when in operation either by a cover or b ythe cooking utensil or utensils placed thereon. As shown, the uppermargins of said wall B are of the same size and shape as the hole a inthe stove-top, so that covers and cooking utensils adapted to fit thestove may also be placed upon the burner when theV latter is upon thestove. The particular burner illustrated in these rfigures is made ofelongated form to fit the single elongated hole comvtwo circular covers.

, brick, pumice-stone, or other porous material,

or of a refractory granular substance, such as sand.

At the middle of the burner, and extending longitudinallyfrom end to endthereof, is an air-chamber F, which communicates with the external airat the ends of the burner by means of suitable inlet-openings f' f',Fig.

Y2. YAt the middle of the top wall ofthe said air-chamber F is located atransverse oil-pas- 1 sage G, one end of which is bent or curveddownwardly toward and extends to a point near the bottom of the troughD.

' G' is the oil-supply pipe,which extends into the air-chamber F of theburner from one end thereof and is connected with the upper part of theoil-passage G. y Over the oil-trough D, and Vbetween the air-chamber andthe adjacent part of the wall B, is formed a combus- Jtion-chamber H,and between said air-chamber and wall B, at the opposite side of theburner, is a passage or opening H', through which the flames and heatedproducts of combustion from the combustion-chamber may pass downwardlythrough the bottom of t-he burner into the stove.

` In the particular construction of the burner herein shown the-severalparts of the burner are cast inone piece, the several walls composingthe parts being disposed as follows: The -lower walls of the air-chamberF and of the oil-trough D are formed by a horizontal bottom plate B',cast integral with the vertical wall B of the burner and forming acontin'uation of the rear part of said wall, as clearly7V shown in Fig.l.

chamber F and also cast integral with the side wall B of the burner,said plate B2 being connected with the bottom plate B' by means of avertical wall B3. Between said wall B3 and the adjacent part of thevertical wallB of the burner is formed the passage H',through whichproducts of combustion from the combustion-chamber H may pass downwardlyin to the stove. At its margin adjacent to the combustion-chamber H thehorizontal wall B2 is provided with a depending flange b', between whichflange and the ange b is formed longitudinal slot or opening f2, throughwhich tion-chamber. At each end of the chamber F is a transverse wallB4, which extends en tirely across the end of the burner and forms theend wall of t-he said chamber F and also the end walls of the passageH', the combustionchamber H, and the trough D. In its part within theair-chamber the wall B4 terminates somewhat above the bottom plate B',so as to form the inlet-opening f', through which air enters the saidchamber F. Said wall B* is connected at its upper margins with thehorizontal top wall B2, which latter is extended at its ends at b2 b2 tothe ends walls of the burner, said parts b2 b2 being preferably arrangedin a plane above the main part of said wall B2. Outside of and parallelwith the wall Btl is another .transverse wall B5, con- `nected at itslower margin with thebottom plate B' of the burner and extendingupwardly to a point near the lower surface of the horizontal wall b2, soas to leave an air-inlet openf2 by the vertical passage f3 between saidwalls B4V and B5. The said wall B5 is desirably provided with a slidingvalve plate or damper B6, adapted to control the openingf', and therebyenable the influx of air to the heating-chamber to be regulated asdesired. The passage G isu preferably cast integral with the top wall B2of the chamber F and extends transversely of the latter, and is providedwith opens at the bottom of the trough D, preferably below the bottom ofthe porous bed E therein, as clearly shown in Figs. l and 3. To supportthe said porous bed E above the bottom of the trough D and therebyafford a space beneath said bed through which the oil may freely ilowfrom the passage G', I have herein shown open metal frames e eas placedin said trough under the porous bed; but studs or projections cast uponthe bottom of the trough y IOO t ing f', which communicates with theopening l IIO Va downward extended tubular part G2, which 8o air'fromthe chamber F enters the combusducts of combustion from the combustionf`chamberH pass horizontally over the top of the airchamber F and thendownwardly through the passage Il', from which t-hey pass to thesmoke-exit passage of the stove, as indicated by the arrows in Fig. 3b.The burner is preferably placed in the stove with the first started andcombustion is comparatively slow by reason of the parts being cold) willaccumulate in the bottom of thechamber F,

, and will there remain until vaporized by the heat of the parts. Airentering the air-heating chamber F through the passages f f f3 at theends of the latter, as indicated bythe arrows, passes to thecombustion-chamber above the porous bed through the slot f2 The walls BB2 B3 of the chamber F are highly heated by the products of combustionpassing over or around said chamber in the manner described, so that theair within the chamber beconies highly heated before its passage to thecombustion-chamber with the result of greatly facilitating the rapid andcomplete combustion of the oil. The air-.entering the chamber is alsoheated to some extent by contact with the walls of the passages f3 f3.

, Another, and for some reasons a preferable,l

construction ina burner embodying the main features of my invention 1sillustrated in Figs. 3, 4, 5, 6, and 7. In this instance, the

burner consists of two separate parts-or castings I andJ, and isprovided with an oiltrough D, a porous bed E, an airfchamber F, anoil-passage G, and 'amcombustion-chamber II, arranged and operatinggenerally in the same manner as before setgforth. The oilpassage G inthis case'ihs: formed by a passage` g, lextending longitudinally of theburner at the side of the latter adjacent to the opening lI and slopingfromV the `outer end of the burner downward to the .middle of thelatter,

and a transverse passage g, sloping from the front towardtlierear of theburner and connecting such passage g with thetrough D. Two of said.passages g are preferably employed,extending from each end of theburner to the cross-passage g, so `that oil may be fed into the burnerfrom either end thereof. The

.-cross-passage g in this instance `passes through the middle of theair-chamber F and divides the latter into two separate compart- Theupper part or vcasting I of the,

ments. burner consists of a vertical wall of ring shape, and the topwall of the air-,heating `chamber F andthe passages g g g arefornied byaplate If, cast integral with the said upper part I and extending fromend tovend of the latter. The bottoni part J of the burner consists,mainly, of a bottom plate J forming the lower walls of the passages g gand the bottom of the air-chamber F andthe trough D and having upon itsside margins horizontal Hanges J2,which restupon thetop` "of the stove.The part I is fitted at its lower margins to the liange J2, the partsbeing secured together, as shown, by screws orbolts jj, passing throughlugs t' upon the casting I and the ange J2. The bottom plate J isprovided with parallel walls js js, which Ifare connected with the wallsj2 j2, and which form,

together'with depending' ianges t" i upon the 4 top plate I', thecross-passage g. Vertical flanges l7"* jt, arranged longitudinally ofthe burner at either side ofl the `central passage g, form the innerwalls of the trough D and separate the latter from the chamber Ff Theend of the passage g adjacent to the troughQD is closed by av dependingpart Izof the plate I', which part reaches to a point near the bottom of the trough, so as to leave a narrow slit or opening for the outfionrof oil from the passage g to the trough. Said part `I2 consists,iasshown, of vertical side walls i2,

forming eontinuations of the anges 'i'.and an end Wall t3, as .clearlyillustrated in Figs. 4 and?. .At the endsof burner the castingI isprovided with depending lianges I3 I3, ter.- minating somewhat above thebottom plate J', soas to form inlet-openings]L14 for the influxkof airto thechamber F. The passages g are closed at their ends by walls f,preferably cast upon the bottom plate J', and provided fwith holes j,through which an oilsupply pipe G maybe inserted. In a burner thusconstructed it. is not necessary that atight joint. should be madebetween the oil-supplyipipeV and the oil-passage of the burner, and apipe G' may be thrust loosely through the holes"`l7"` into either 4oneof the passages g, and the oil dripping or iowing from the said pipewill run downward to the center of therburner and thence into theoil-trough- Dthrough the trans:

verse passage g. The passage Il for-the exit of4 the productsof`combustion frointhe burner downwardly into the stove is in thisinst-ance formed between the flange jf., constituting the outer wallofthe oil-passages` g g; and the adjacent portion of the,walll,gand

the heated products of combustion .pass over or against the vesselforcover i1-pon: the. burner and the 4top of the lair-chamber., and .then

`downwardly through said passage Haz', So as to accomplish the heatingA:of the walls of .the chamber and the air therein in the same manner asbefore described.

I have shown the castingliasprovided'witheV a mica-ecovered opening I4in its.` part adjaj cent to the combustionchamber, whereby the conditionof theiiame within the burnermay be observed without opening the,ilatter.

' It maybe here remarked in connection with the form kof burners shownin. Figs. 1 to 7that said burners are more especially intended forburning lheavy oils or liquid hydrocarbons IOG IOS

IIO

having a relatively high flashing or Vaporizing point, and not forburning a light hydrocarbon, such as gasoline. It is not int-ended,therefore, in these burners that the oil shall become vaporized beforereaching the point of combustion and thereafter burned in the form ofvapor, but the oil supposed to flow in a heated state into theoil-trough and to be there consumed.

In Figs. S, 9, and lO is shown another form of burner, which is adaptedfor use in burning both oil and gas or vaporized hydrocarbons. Thisburner is generally similar to that illustrated in Figs. 1, 2, and 3,and embraces a 'casting M, provided with vertical side walls M', abottom wall M2, a partial top wall M3, and a side wall M4, locatedinside of and parallel with the front outer wall of the burner, theseseveral walls forming a combustionchamber Il, an air-heating chamber F,and an outlet-passage H for the downward passage' for theproducts ofcombustion to the smokeexit passage of the stove. At the side of thechamber F adjacent to the combustion-chamber is formed a longitudinaltrough N, which trough is arranged over a longitudinal slot h, by whichair from the chamber F passes into the combustion-chamher H. Anoil orgas supply pipe N is inserted through the end wallv of the burner andopens into the space of the air-chamber at aV point above the trough N.Upon the bottom wall M2 of the burner and extending beneath the trough Nis an'oil-trough D, provided with a porous bed E, said trough D beingused when oil is used as a fuel. A rib or flange m divides the trough Dfrom the main part of the chamber F. Air is admitted to the air-chamberF at the ends of the burner through a tortuous passage f5, form ed inthe casting M, as clearly shown in Figs. l, 2, and 3. In the use of thisform of burner with oil, however, the oil delivered through the pipe 'Nflows into the trough N and becomes distributed therein throughout theentire length thereof. When the trough has become lled, the oi-loverflows therefrom and drips into the trough D "and is burned at thetop of the porous bed ftherein.

The trough N is preferably formed integral with the adjacent top wall'M3of the chamber F, being connected with said top wall by a connectingpart m', Fig. 8,Which forms one wall of the combustion-chamber, so

the burner is used for gas or vapor, the porous bed E is obviously notrequired.

Figs. 11, l2, and 13 show a burner embodying the mainfeatures ofconstructionpresent in the burners hereinbefore described, but differingtherefrom in several particulars.` In

this instance the body of the burner consists of a single casting L,having side Walls and a partial bottom open at its top and made of theproper shape atits lower margin to fit the hole in the stove-top. Theburner shown in Figs. l1 and l2 is made of oval form and adapted to fitover the large hole in a stovetop, while that shown in Fig. 13 iscircular and adapted to be placed over one of the single round holes ofa stove. The casting L is shown as provided with a rabbet 1 about themargins of its lower edge, fitting the rabbeted margins of the hole inthe top plate, as clearly shown in the drawings. The open top of thecasting L may be closed by the presence thereon of a vessel or cookingutensil, as indicated at K; but it may be provided with metal coverssuch as are commonly employed on stoves,and for this purpose its uppermar- 'gins are shown as made to correspond in size and shape with thehole in the stove to which the bottom of the burner is fitted, so thatwhen the covers are removed from the stove they may be placed upon thetop of the burner. In the bottom or lower part of the casting L,adjacent to one of its sides, isan oil-trough D, within which is aporous bed E. In the casting between the bottom of said trough D and thelower horizontal surface of the casting is formed a chamber or recessL', communicating with the said trough D by means of passages Z. Anoil-supply pipe Gr communicates by passage Z2 with the interior of thesaid recess' L', whereby oil is fed to the said recess and to the troughD, which it enters by passing through the apertures Z Z. The recess Lextends from end to end of the burner, is preferably arranged to occupythe entire space beneath the troughs D, and the oil is desirably fed tothe central portion of said recess by extending the passage Z2 through awall or partition Z3, reaching from the end of the casting to a pointnear the middle of the recess, as clearly shown in Fig. l2.

F indicates an air-heating chamber arranged longitudinallylof the burnernear the middle of the latter and at one side of the trough D, saidchamber being provided at one end with openingsff for the admission ofair thereto, and having at its side adjacent to the trough D alongitudinal slot or opening Z4, by means of which air for supportingcombustion passes from the airheating chamber to the combustion-chamberH, located over the oil-trough. The inlet air-openings ff to the chamberF are controlled by a damper, herein shown as consisting of a revolvingplate O, apertured to correspond with the openingsfj', and provided witha handle 0, by which it may be turned. The opening Z4 may be, ifdesired, provided with a sliding plate Z5, whereby the size of the saidopening may be increased or decreased, as found necessary or desirablefor the proper working of the burner.

When the burner is placed upon thel stove and its top is closed byplacing thereon avessel or suitable cover, the operation ofv the de- ICOIIO

vice is as follows: Oil supplied through the pipe G enters the chamberor passage L, the walls of which are kept at a high heat during theoperation of the burner, so that saidy oil is heated before its passageinto the trough D. Air for supporting combustion enters the chamber F,becomes heated therein,and then passes through the opening Z4 into thecomupon the bottom surface of said casting, and

thereby greatly aid in the heating of said airchainber and of the partof the casting containing the said passage L.

The general construction described is the same either in the case of thelong burner shown in Figs. l0 and 1l, or in that of the round burnerillustrated in 4plan View, Fig. l2.

l I claim as my invention- 1. A burner consisting of a ring-shaped Icasting or shell adapted to t at its lowerg utensils, acentrally-arranged air-heating chamber located within the said castingor shell, an oil-holding trough located between one side wall of thechamber and the shell, and the said chamber being provided with a'slotor opening for the admission of air from the chamber to the main trough,and the side Wall of the chamber opposite the said trough beingconstructed to constitute one side of an opening or passage leadingdownwardly through the shellor casting to the space between the stoveupon which theburner is placed, substantially as described'.

2. A burner comprising a casting or shell provided at its top with ahole for cooking utensils, and with a bottom wall having an exit-openingat one side for products of combustion, a central air-chamber, ,anoil-holding trough located at the side of said airchamber opposite theexit-opening, and an oil-supply passage formed in and by the Walls otsaid air -cha1nber, substantially as described.

In testimony that I claim the foregoing as my invention I aix mysignature in presence of two Witnesses.
